Abstract
Apparatus for automatically performing multiple chemical analyses of a plurality of liquid specimens. The apparatus comprises apparatus for loading a plurality of test samples from each specimen into a row of reaction vessels. As the reaction vessels are transported to a determinating apparatus, other apparatus adds reagents to preselected ones of the reaction vessels a predetermined time before the reaction vessels reach the determinating apparatus. In particular, each of the several sample containers initially containing the specimens is transported in a track or the like in parallel with the one of the several rows of reaction vessels containing the test samples from the specimen toward the determinating apparatus. Microswitches engage each of the sample containers along the way, enabling the reagent adding apparatus to add selected reagents to the parallel row of reaction vessels. The reacted test samples are automatically analyzed by the determinating apparatus and the results output on a paper tape or the like. In addition, apparatus is provided for automatically removing the sample containers from the track after the determinations have been completed and depositing the containers in predetermined sequential order in a tray.
